    Hi,
    I am new in Rad control implementation in ASP.NET,I am using two RadListBoxes in my project.
    when i select an item at Source RadListbox then destination RadListBox is flickering,
    i used Update panel the whole page is not flickring but only inside RadListBox(at Destination) is flickering.
    i used OnTexrtChanged server event and made autopostback=true at source side.

    so how to avoid flickering after postback happen?

    Please support.

    Hi Santosh,

    Could you provide some sample code so that we can try to reproduce the issue locally?

    Hi Bozhidar,
    I had solved this problem by using RadAjaxPanel,
    But now my main problem is RadListbox item is not transferring to destination Radlistbox after publishing in to IIS 6,
    but transfer functionality is working fine locally in my Visual studio 2010 and no build errors at locally.

    aspx Code:

     <telerik:RadAjaxPanel ID="radajaxpnlMain" runat="server">
    <telerik:RadListBox runat="server" ID="RadListBoxSource" OnItemDataBound="RadListBoxSource_ItemDataBound"
     OnTransferring="RadListBoxSource_Transferring" AllowTransferOnDoubleClick="true"
    AutoPostBack="true" EnableDragAndDrop="false" AllowTransfer="true" SelectionMode="Multiple"
    TransferToID="RadListBoxDestination" AutoPostBackOnTransfer="true" Skin="WebBlue"
    OnSelectedIndexChanged="RadListBoxSource_SelectedIndexChanged">
    </telerik:RadListBox>
                                   
    <telerik:RadListBox runat="server" ID="RadListBoxDestination" AllowTransferOnDoubleClick="true"
    AllowTransferDuplicates="false" EnableDragAndDrop="false"
    OnSelectedIndexChanged="RadListBoxDestination_SelectedIndexChanged" Skin="WebBlue"
    SelectionMode="Multiple" OnItemDataBound="RadListBoxDestination_ItemDataBound"
    AutoPostBack="true" AutoPostBackOnTransfer="true">
    </telerik:RadListBox>
    </telerik:RadAjaxPanel>



    Please Support.
